Ipeyinti ethambileyo yangaphandle

Ubume beSanti: Ngokudibanisa inani elincinci lesanti ye-quartz efanelekileyo, imveliso inikezela ngokugubungela okuphezulu, ukusetyenziswa okuphantsi kwimitha yesikwere, kunye nokusebenza kakuhle kweendleko zokwakha. Ubume bubuthathaka, kwaye ukubonakala kuthambile. 

Ifilimu yepeyinti ineempawu ezinamandla zokwelula, okwenza ukuba zilungele ukugubungela iincinci ezincinci kwiindonga. Imveliso ibonisa ukuguquguquka okukhethekileyo kunye namandla okuzibamba kwindawo ephantsi kunye nobushushu obuphezulu, iyenza iguquguquke kakhulu kwiimozulu ezahlukeneyo, ngakumbi ezo zinokuguquguquka okubalulekileyo kobushushu.

Ukulinganisa: Iputty erhabaxa 1-2 amaxesha, 2-3kg/m, iputty ecolekileyo ixesha eli-1, 1kg/m2

Inkulumbuso: I-Alkali-resistant emhlophe primer yodonga lwangaphandle 1 ixesha, 0.15kg/m

Ukwaleka okuphakathi: I-elastic medium coating ibrashi yepeyinti ixesha eli-1: 0.25-0.3kg / m2

Ukwaleka komphezulu: Ipeyinti eludongeni olulastiki olukhulu lwangaphandle 2

Umgangatho woMphezulu: Xuba iputty ngokomlinganiselo ochaziweyo de udityaniswe ngokulinganayo. Kufuneka ingabikho kwi-powder, i-clumps, okanye i-particle enkulu, kunye ne-viscosity ephakathi. Gcoba i-putty ecolekileyo elungisiweyo ngemela ye-putty kwiidyasi ezi-1-2, ukugudisa nge-scraper ngaphambi kokuba umphezulu womiswe, uqinisekise ukuba usezingeni kwaye uthe tye. Nje ukuba i-putty yome ngokupheleleyo, sebenzisa idyasi enye ye-putty, kwaye emva kokumisa umphezulu, sebenzisa i-putty vacuum sander ukuze ugudise kancinci umphezulu. Umcaba ofunekayo kufuneka ube ≤1mm.

Inkulumbuso: Emva kokuxuba ngokucokisekileyo i-primer emhlophe echasene ne-alkali yangaphandle, ingasetyenziswa ngokuthe ngqo. Ukuba i-viscosity idinga ukulungiswa, kufuneka ihlanjululwe ngumntu ochongiweyo ngokomlinganiselo omiselweyo, ukuqinisekisa ukuba amanzi adityanisiweyo awadluli i-10% yomthamo wepeyinti. Faka isicelo se-primer esilungisiweyo usebenzisa i-roller yoboya, ukugubungela iikona kunye nezikhewu nge-brush yoboya. Qinisekisa ukuba iingubo ziyafana, akukho mabala aziphosiweyo okanye ukopha.

Ukwaleka okuPhakathi: Emva kokuxuba ngokucokisekileyo ipeyinti yokugquma i-elastic textured intermediate coating, inokusetyenziswa ngokuthe ngqo. Ukuba i-viscosity idinga ukulungiswa, yongeza amanzi ngokulinganayo, kunye ne-dilution ratio engadluli kwi-5% yomthamo wepeyinti. Faka ipeyinti yepeyinti usebenzisa i-honeycomb roller kwingubo enye, uqinisekise ukuthungwa okufanayo kwaye akukho mabala alahlekileyo okanye iiprotrusions ezibukhali. Eli nyathelo linokwenziwa ngokweenkcukacha zomxhasi.

Idyasi ephezulu: Emva kokuxuba ngokucokisekileyo ipeyinti eludongeni lwangaphandle elastiki, inokusetyenziswa ngokuthe ngqo. Ukuba i-viscosity idinga ukulungiswa, yongeza amanzi, kunye ne-dilution ratio engadluli kwi-5% yomthamo wepeyinti. Faka i-topcoat elungiselelwe usebenzisa i-roller yoboya kwiidyasi ezimbini, kunye nekhefu lokubuyisela ubuncinane ubuncinane kwiiyure ezi-4. Kwiikona kunye nezithuba, sebenzisa ibrashi yoboya ngoncedo. Qinisekisa ukuba iingubo ziyafana, akukho mabala aziphosiweyo okanye ukopha.
